Answer:
b)0, yes
Step-by-step explanation:
Given:
Vectors (4,8) . (6,-3)
Finding inner product of vectors:
= 4x6 + 8x-3
=24-24
=0
Now to check the angle between them using formula a.b=|a|.|b|cosθ
|a|= 
=8.9
|b|=
=6.7
Putting values of a.b=0 and |a|=8.9, |b|=6.7 in a.b=|a|.|b|cosθ we get,
0= 8.9(6.7)cosθ
cosθ =0
θ=90 degrees
Hence the two vectors are perpendicular !

=========================================
Explanation:
Each value can be found in Pascal's triangle. You can also use the nCr combination formula to get each value. The nCr formula is

The value of n represents the row number. The r value is the column number, so to speak, for each row.
The first odd number is 1. The next is 2 more than the previous one.
It's an arithmetic sequence.
The general term of an arithmetic sequence:

a_n - n-th term
a_1 - first term
d - common difference.
We have

Substitute:

<h3>Answer: 137th odd number is equal 273.</h3>
